PURPOSE:To make it possible to perform automatic detection of the posture of a laser gun by providing a plurality of posture detecting parts comprising incident parts and light receiving parts within a machining head. CONSTITUTION:A signal which is transduced from light into an electric output V1 in a photodetector S1 is amplified. Thereafter the noise component is removed through a filter, and a digital signal is outputted. Output data, i.e., data such as the amount of change in codes and distances indicating the fact that on which side of the regular position a luminescent spot a1 is located, i.e. on the far side or the near side, are sent into a sensor computer SPC through an interface. In the computer SPC, the computation of the four measured data is performed in real time. Posture control data are sent into a controller MCP for machining equipment. The controller MCP generates a driving power for the posture control so that the posture of a laser gun G is properly corrected. In this way, automatic posture control during the operation can be performed. |
